Nonetheless, also in the latter populations, CNDP1 variants were found to contribute to susceptibility for DKD (McDonough et al. 2009), suggesting that apart from the (CTG)n repeat also SNPs within the CNDP1 gene, i.e., rs4892247 (McDonough et al. 2009), rs62099905 (Zhang et al. 2020) and rs4891564 (Mota-Zamorano et al. 2021) might influence the course of DKD. This evidence concerns the gene CNDP1 and diabetic kidney disease.
